17. The Hill School – $59,050 Yearly Tuition
The Hill School just 40 miles outside of Philadelphia was ranked one of the most elite boarding schools in the country by Business Insider. And it’s no wonder. Hill School alumni include a secretary of state and a secretary of treasury, a long list of senators, current Pennsylvania Governor Tom Wolf, and even President Donald Trump’s son, Donald Trump Jr.
At The Hill School, visitors will spot students donning their “formal academic dress code”. This requires boys to wear a coat and tie and girls to wear a blazer and “appropriate collared Oxford shirt”. These uniforms are required to be worn all day, including for chapel services, sit-down meals, and “required evening performances”.
